Keto Sourdough Starter: Arrival, Feeding & Care Guide
Just received your Living Dough keto sourdough starter? Start feeding it as soon as possible after arrival. This guide explains the first feeding, flour options, daily maintenance, and refrigerator storage using the care instructions supplied with your starter.
Your starter may not look bubbly straight out of the package. Give it consistent care and time to regain activity after shipping.
Day 1: Feed your keto sourdough starter
- Transfer the entire starter you receive into a clean jar, bowl, or container with plenty of room to rise.
- Add 2 ounces by weight of water and 2 ounces by weight of flour. The supplied sheet lists approximately 4 tablespoons of water and 5 3/4 tablespoons of flour. Flour volume varies, so use the weight measurements for consistency.
- Mix thoroughly. Use bottled, spring, or filtered tap water.
- Keep at room temperature while you monitor its return to activity.
Which flour should you use?
Our care sheet recommends lupin flour as the first choice for this starter. It also lists coconut flour and almond flour as options, including a blend of these flours.
Different flours absorb water differently, so watch the consistency rather than expecting every flour to behave the same way. These are feeding options from the care sheet, not a nutritional analysis of the starter or finished bread.
Day 2 onward: Feed at a 1:1:1 ratio
Feed every 24 hours using equal weights of starter, flour, and water. This is a 1:1:1 feeding ratio, written as starter:flour:water.
For example, feed 1 ounce of starter with 1 ounce of flour and 1 ounce of water. If you retain more starter, increase the flour and water to match its weight.
Use weight, not equal cups or spoonfuls. Flour and water do not weigh the same by volume, and different flours have different densities.
For more measurement examples, read our 1:1:1 sourdough starter feeding guide. Continue using this page's flour choices and care routine for your keto starter.
Adjusting consistency
The supplied instructions describe a grainy pancake-batter consistency. If your starter becomes thicker, you can add a little more water. Adjust gradually because lupin, coconut, and almond flour can absorb water differently.
When to discard before feeding
Once your starter is active, or after three days of feeding, remove some before feeding to keep the amount manageable. Feed the starter you retain using the same 1:1:1 ratio by weight.
One maintenance example from the care sheet is to retain 4 ounces of starter and add 4 ounces of water and 4 ounces of flour. Weigh these ingredients rather than using a fixed cup conversion across different flours.
When is your keto starter ready to bake with?
The supplied guide allows from one feeding to as many as six days of feeding for activity to return after shipping. Watch for a significant rise or bubbling after feeding.
Plan to begin your recipe when the starter is roughly at its peak size. The care sheet suggests approximately 3–6 hours after feeding, but temperature, flour, and starter activity affect the timing.
This starter may not bubble or double as dramatically as a traditional sourdough starter. Observe its usual pattern instead of relying on doubling alone.
Countertop care and refrigerator storage
Keep feeding an active countertop starter every 24 hours using equal weights of retained starter, flour, and water.
If you are not using your active starter regularly, the supplied routine calls for storing it in the refrigerator and feeding it every 5–7 days. Before baking, allow time and feedings for it to return to its usual activity.
Keto starter feeding questions
What if my starter is sluggish?
The care sheet suggests a larger 1:3:3 feeding for a sluggish starter: one part starter, three parts flour, and three parts water by weight. Contact us if you need help adjusting your feeding routine.
You can also read our sourdough starter feeding troubleshooting guide. Keep this page's flour options and storage schedule in mind.
Can I use cups instead of a scale?
A scale is the more consistent option, especially when changing flours. Follow the equal-weight feeding ratio rather than assuming that one cup of each ingredient will give the same result.
Why doesn't it rise like my traditional starter?
Different flours can produce different textures and activity patterns. The supplied instructions note that this starter may show less dramatic bubbling or doubling than traditional starters.
